' To all whom it may concern.-

Be it known that I, PIOTR JAsINsKI, a subject of the King of England, residing at Vvelland, Prov. of Ontario and Dominion of Canada, and I, JAN SMOGALA, a subject of the King of England, residing at Welland, Prov. of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Antisubmarine Devices, of which the following is a specification.

'This invention relates to improvements in antisubmarine devices, and particularly to types in which a net may be held extended at some distance from the hull of the ship so as to completely encircle the same below the water line.

The principal object of the invention is to provide means whereby the extending nets may be quickly and rigidly secured or released from their supports by mechanism operated from the deck of the ship.

These and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure 1 is a side elevational View, showing a conventional type of ship, together with the surrounding net held by supports made in accordance with the invention.

Fig. 2 isan enlarged fragmentary trans verse sectionalview, taken through a portion of the hull of the ship, showing the net and its supporting means. 1

Fig. 3 is a top plan view of the same, and

Fig. l is a perspective view, bracket supports, by which the nets are suspended.

Engaged with the hull 10 of the vessel are a plurality of equally spaced bracket supports 14 in which are fixed diverging bars 15, other lower brackets 18 being also secured to the hull of the vessel from which extend upwardly and outwardly bars 19, their outer ends being engaged in suitable openings formed in elements 20 in which are also rigidly secured the outer diverging ends of the bars 15.

Formed in the elements 20 are outwardly extending rigid jaws '22, containing semicircular recesses 23, adapted to receive a rail 24, from which the net 25 is suspended.

In order to hold the rails 24: rigidly enshowing the gaged within the elements 20, caps 26 are provided, the same having recesses op osed to the recesses 23,and extending shan s 27, which are engaged upon spindles 28, pivoted in the upper portion of the brackets 20.

' Afiixed upon the center of the spindles 28 is a lever 30 extending'upward, and joined to it a link 31, extending toward the hull of. the ship, parallelwith the plane ofthe support bars 15, and is connected at its inner end with one arm '33 of a bell-crank lever, pivoted in clip brackets 34: secured upon the angularly disposed support bars 15.

The outer arm 35 of the bell-crank lever has engaged with it a link 36, engaging the outstanding arm 38 of another bell-crank lever, pivoted upon brackets 39, secured to the upper portion of the hull of the ship, the outer arm 10 of the bell-crank lever being pivoted to the end ll of a screw 12 operable within fixed brackets 43 secured upon the deck of the ship.

This screw is provided with an operating crank handle 44:, by which it may be manually turned. Thus, when it is desired to release the rails 24, which support the net 25, the crank handle 4.4. is actuated so as to 0p erate the severalbell-crank levers, raising the lea'for cap elements 26, so that the rails 21 can be readily removed.

From the foregoing it will be seen that an effective device has been disclosed in which the supporting rails may be engaged at any time, and when the caps 26 have been raised, it is possible to remove the rails 24;, together with the nets.

Having thus described our invention'what we claim as new, and desire to secure by Letters Patent, is

In a device of the character described, in combination, a plurality of upper and lower bracket supports secured to the outer hull of a ship, an outwardly extending bar secured in each of said brackets, elements secured to the outer ends of each pair of bars extending from an upper and a lower bracket respectively, outwardly extending. rigid jaws formed in said elements having semi-cylindrical recesses adapted to receive a rail, caps "ournaled in said elements, cooperative with said jaws to secure said rail in position, a lever formed with spindles upon which the shanks of said caps are engaged, a bell-crank lever mounted in clips on the bars extending from the upper brackets, connections vbetween said bell-crank engaged invsaid bracket supporting. said leverand the lever of said caps, a 1 611 screw, said screw actuating thelast 'named 10 crank lever connected to a bracket secured bell-crank lever. to the upper: part of the hull, alink con- In testimony WheIeOff'We havet affixed our 5 necting onearm of the first named bellsignatures.
